Abstract

The driven pulley is part of a continuously-variable transmission (CVT). The driven pulley comprises two coaxially-disposed sheaves defining between them a belt-receiving groove. It also has at least two axisymmetric ramp surfaces attached to one of the sheaves and at least two axisymmetric followers attached to the other sheave, each ramp surface being engageable by a corresponding one of the followers. At least some of the ramp surfaces are provided on corresponding ramp holders that are independent from the sheaves. A method of modifying the settings of a driven pulley and a method of assembling a driven pulley also disclosed.
